Here's the latest from the Common App regarding formatting issues that some students and schools have been having with admissions essays, resulting in large blocks of text with no paragraph breaks:
"Essay Formatting. We have informed all member colleges that errors in the text-to-PDF conversion process have the potential to produce essays that contain unusual formatting, including inconsistent fonts and errant paragraph breaks. We have assured colleges that students have no control over this formatting and that these types of errors are our fault, not the students'. We have heard confirmation from many colleges that they will not in any way penalize students for a technical problem that is out of their control."
